RESUMEN
BACKGROUND: This study focuses on the efficacy and 2-year outcomes of ultra-low-dose radiotherapy (RT) in treating primary and secondary ocular adnexal lymphoma (OAL). METHODS: A retrospective analysis was conducted on patients with OAL between 2017 and 2022, treated with 4 Gy of RT. The primary and secondary outcomes assessed were response rate, progression-free survival, and lymphoma-related death. RESULTS: Twenty-one patients with primary and secondary OAL of diverse, presentations, subtypes, and stages were included. The orbital tumors had an average size of 17 × 16 × 16 mm. Of the 14 primary OAL cases, 3 (14%) had T1N0M0 disease, 8 (38%) T2N0M0, and 3 (14%) T3N0M0 (AJCC 8th edition staging); of the 7 secondary OALs, 4 (19%) were stage IE, 2 (10%) stage IIE, and 1 (5%) stage IIIE (Ann Arbor staging). Ultra-low-dose RT yielded a 95% complete response rate and 100% progression-free survival rates, both locally and systemically at 2 years. Mild dry eyes were reported in 14% of patients as a late treatment toxicity. CONCLUSIONS: Ultra-low-dose RT emerges as an effective and well-tolerated treatment approach for OAL. Our findings support the use of 4 Gy, showcasing high complete response rates (95%) and durable disease control without significant local relapses over an average follow up of 27 months. Our results align with earlier investigations, validating the curative potential of ultra-low-dose RT and reinforcing the concept of achieving favorable outcomes with minimal intervention. This approach may potentially alleviate the burden of long-term ocular side effects associated with higher radiation doses, enhancing the overall quality of life for OAL patients.
RESUMEN
The focus of this case study is the delayed diagnosis of a perinatal HIV transmission, which was identified when the infant reached 4 months of age, and the social conditions and structural determinants that contributed to the increased transmission risk. Despite adhering to the diagnostic testing protocols and neonatal antiretroviral (ARV) guidelines of the New York State Department of Health, this transmission still occurred. This transmission event prompted strategies to address criminalization of substance use during pregnancy and a reevaluation of the HIV testing and treatment protocols, including the timing of testing. Obtaining a diagnostic specimen at birth before initiating prophylactic or presumptive therapy, without causing delays in therapy, and incorporating HIV-1 DNA or RNA testing 2 to 6 weeks after discontinuing ARV therapy might have facilitated earlier detection and a quicker resumption of ARV therapy for this high-risk infant. Subsequently, the New York State HIV perinatal testing guidelines were updated. These changes included the recommendation to obtain a diagnostic specimen at birth before initiating ARV medications, whenever feasible, without causing delays in ARV initiation. Additionally, an extra virologic diagnostic test is recommended at 2 to 6 weeks after discontinuing ARVs for infants at high risk of perinatal HIV transmission, especially those with possible DNA or RNA suppression due to ARV prophylaxis or presumptive HIV therapy.

Purpose: To evaluate percutaneous triamcinolone (TA) injection efficacy in treating upper eyelid retraction (UER) for Australian thyroid eye disease (TED) patients. Methods: We conducted a retrospective analysis across 8 years and multiple diverse Australian centres identified UER patients who received TA injections. A single operator administered 40mg/1ml TA through upper eyelid skin. Assessments at 4-6 weeks and subsequent eyelid measurements gauged treatment response and complications. Results: 24 patients and 25 eyelids were included in the study. 91.6% were female, mean age 40.8 ± 10.3 years with mean follow-up of 17.5 months (± 18.5). Pre-treatment MRD1 was 6.2mm ± 1.4, and we observed a mean improvement of 2.2mm from pre-treatment to post-treatment (p<0.001). The mean UER measurement before treatment (defined as MRD1 - 4.0mm) was 3.0mm ± 1.3 (range, 0-6mm). After treatment, the mean UER measurement was -0.1mm. Quality of life (QOL) assessment improved significantly, from pre-treatment score of 4.13 ± 2.4 to post-treatment 8.0 ±1.7 (p<0.001). Conclusions: Percutaneous injection of TA is an effective and safe treatment option for UER in patients with TED. This technique can be performed without upper eyelid eversion, which makes it more tolerable for patients and less complex for the operator compared to the transconjunctival injection approach. Our results show a significant improvement in MRD1 and UER, as well as patient QOL. Moreover, we found a low rate of complications (4.2% induced ptosis) and no cases of raised intraocular pressure. Percutaneous TA injection can greatly reduce the need for eyelid lowering surgery in this patient population.
